These days, I've been watching on-chain for people chasing "sandwich + arbitrage," thinking I'm catching opportunities, but maybe I'm just contributing to others' fees + slippage... A few days ago, I got a little eager and made a move, but then gas prices skyrocketed, and my execution price was clearly squeezed, which really woke me up. Now, whenever I see pools suddenly experiencing high volume, I pause first: is it really an opportunity, or is someone ahead of you collecting transaction fees?

Staking unlocks and token unlock calendars are also being discussed repeatedly, and the anxiety about sell pressure makes it easier to click confirm impulsively. The more anxious, the more likely I am to make mistakes. Anyway, I now prefer to use limit orders instead of market orders, trying small amounts first—better to be slow than sorry.

What I don't regret is... at least I learned not to compete with mempool for speed; if I can't beat it, I might as well pay less tuition.
